Data acquisition and communication module realizes signal acquisition between sensor and host to detect analog signals.WJ128 series products can be used in RS-232/485 bus industrial automation control system, 4-20mA/0-5V signal measurement, monitoring, industrial field signal isolation and long-line transmission, etc.
Products include power isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication.Up to 255 WJ128 series modules can be connected to each serial port. ASCII code communication protocol or MODBUS RTU communication protocol are used for communication. Baud rate can be set by code. It can be hung on the same RS-485 bus with control module from other manufacturers to facilitate computer programming.
Data acquisition and communication module is an intelligent monitoring and control system based on single-chip computer. All user-set configuration information, such as calibration value, address, baud rate, data format, check sum status, etc., are stored in non-volatile memory EEPROM.

Data acquisition and communication module, which can be used to measure eight voltage or current signals.
1. Analog signal input
12-bit acquisition accuracy, 8 analog signal inputs.All signal input ranges are fully calibrated before the product leaves the factory.In use, the user can also easily program the calibration itself.For specific current or voltage input ranges, please refer to product selection.
2. Communication protocol
Communication interface: 1-way standard RS-485 communication interface or 1-way standard RS-232 communication interface, specify when ordering.
